# Nano Banana

**Fast, versatile image generation and editing**

Nano Banana is daisy's most versatile image model, supporting text-to-image generation, editing, and markup editing. It's fast, affordable, and available in Standard and Pro tiers.

## Models

| Tier     | Model           | Resolution | 1x | 4x |
| -------- | --------------- | ---------- | -- | -- |
| Standard | Nano Banana 2   | 1K         | 7  | 27 |
| Pro      | Nano Banana Pro | 4K         | 16 | 59 |

Toggle **Pro** in the toolbar to switch between Standard (1K) and Pro (4K) output. The Pro toggle controls both the model tier and the output resolution — when Pro is on, you automatically get 4K output.

## Capabilities

### Text-to-Image

Generate images from a text prompt alone. Describe what you want and Nano Banana creates it from scratch — no source image required. Available from both the "Generate Image" and "Edit" workflows.

### Edit

Provide an existing image and describe changes in natural language. Nano Banana transforms it while preserving the overall composition. Works well for style changes, color adjustments, adding or removing elements, and atmosphere shifts.

### Markup Edit

Nano Banana's unique capability — not available on any other model. Draw an outline directly on the image to define a specific region, then describe what you want changed. The model edits **only the outlined area** while leaving the rest of the image untouched.

This gives you precise spatial control over edits. Use it when you want to change a specific part of an image (e.g., change just the sky, replace an object, modify a face) without affecting the surrounding content.

### Search Grounding

Nano Banana can use **live web search** to ground image generation in real-world information. When enabled, the model searches the web before generating, producing images that reflect current events, real places, recent products, and other up-to-date details.

**When to use Search Grounding:**

* Generating images of real-world subjects that change over time (e.g., "the latest Mars rover on the Martian surface")
* Creating content that references current events, trending topics, or recent releases
* Producing accurate depictions of real locations, public figures, or products

**When to skip it:**

* When generating purely creative or fictional content
* When working with reference images (search grounding works best with text-to-image prompts)

Toggle the **globe icon** in the toolbar to enable or disable search grounding. No additional credits are required.

### Reference Images

Upload up to **5 reference images** to guide generation. Reference images help the model understand the style, composition, or subject you're aiming for.

{% hint style="info" %}
When reference images are uploaded, the aspect ratio selector is hidden — the output automatically matches the aspect ratio of your reference images.
{% endhint %}

## Options

### Pro Toggle

Switches between Nano Banana 2 (Standard, 1K resolution) and Nano Banana Pro (4K resolution). The Pro toggle simultaneously controls the model tier and enables high-resolution output. Credits increase from 7 to 16 per image.

### Aspect Ratio

Choose from **1:1** (square), **4:3** (landscape), **16:9** (widescreen), or **9:16** (portrait/vertical). The aspect ratio selector is hidden when reference images are uploaded — the output automatically matches your references.

### Search Grounding Toggle

Enable web-grounded generation. The **globe icon** appears in the toolbar when Nano Banana is selected. When active, the model uses live web search to inform image generation, producing results that reflect current real-world information. Available on both Standard and Pro tiers at no extra credit cost.

### Markup Edit Toggle

Enable markup editing mode. When active, you can draw directly on the image to outline the area you want edited. Your text prompt then describes what to change in that specific region. Only available on Nano Banana.

### Output Count

Generate **1**, **2**, **3**, or **4** images per request. Generating 4 at once (batch) gives you a \~6% per-image discount:

| Count     | Credits (Standard) | Credits (Pro) |
| --------- | ------------------ | ------------- |
| 1         | 7                  | 16            |
| 2         | 14                 | 32            |
| 3         | 21                 | 48            |
| 4 (batch) | 27                 | 59            |
